Additionally, although the trains used on the Red Line are generally considered to have a 25-year lifespan, 74 of the route’s 218 trains are 40 years old and should have been replaced 15 years...

...Rose says. Michael Jasny, senior policy analyst with the National Resources Defense Council, agrees. "Airguns fundamentally alter the fabric of life in the ocean and they do it at an enormous scale far beyond that of a ship monitor to judge," he says. Airguns have been developed during the lifespan of marine mammals that are alive today, so they "haven't evolved to handle the industrial noise we're putting into the ocean, which has doubled every decade for the last 50 years," Jasny adds.

...Vapours,” and the ebb and flow of these remnants shape a strange topography; the result lies somewhere in between the new and the old and meshes the two in a vaguely discordant harmony.

...rapamycin delayed the deaths of the longest-lived male mice by 101 days and by 151 days in the longest-lived females - the equivalent of about 13 years on average in humans - compared with mice with no treatment. In terms of life expectancy when treatment began (or average remaining lifespan when the mice were 600 days old), that translates to an increase of 38% in female mice and 28% in males...

...also prolonged life in lab mice. But the new finding by Strong and his colleagues "more clearly identifies the [target of rapamycin] pathway as important across species." It may guide researchers to target different proteins in the same pathway. "If those proteins react the same way to extend lifespan, then we might be able to get rid of unwanted side effects," says Strong...
